@dennishlewis of Viva

What is Viva?
VIVA introduces a concept called Proof of Authority; a system that delivers instant transactions and seamless consensus. Our CTO, William Banks contrasts various models in his Game of Chains article published on Steemit.(1) But to summarize, Proof of Authority disposes of certain egalitarian notions involved in weaker consensus models and replaces them with cryptographic signature proofs and business contracts enforced by the network and also backed by the network. ~Viva Coin Blog~

@cm-steem of Gridcoin

##What is Gridcoin?
Gridcoin (Ticker: GRC) is a decentralized, open source math-based digital asset (cryptocurrency). It performs transactions peer-to-peer cryptographically without the need for a central issuing authority.
Gridcoin was the first block chain protocol that delivered a working algorithm that equally rewards and cryptographically proves solving BOINC (Berkeley Open Infrastructure for Network Computing) hosted work, which can be virtually any kind of distributed computing process (GPU/CPU/Sensor/Etc).
BOINC is an open-source volunteer oriented computing grid that combines the processing power of all individual users for the purposes of scientific research. It's free, and harnesses the unused clock cycles from processors and graphics cards to attempt to cure cancer/aids/ebola/malaria, map the milkyway, crack enigma codes, etc..
Gridcoin rewards BOINC computation using the Distributed Proof of Research (DPOR) reward mechanism, which is a combination of Proof of BOINC (POB) and Proof of Stake (POSv2).
Proof of Work (POW) consensus mechanisms are not utilised by the Gridcoin network, making the Gridcoin cryptocurrency network far more energy efficient than any existing POW cryptocurrencies.
